[Solved] Gridview RowDetails Layout problem

[JJ Loubser]

I used demo: http://demos.telerik.com/silverlight/#GridView/RowDetails in my project works fine, we just need to change the layout of the rowdetails, it must be in a block on the right side that never goes away thus empty or details equels to the selected row, must look like this in pic<gridview.png>. Must we just change a flag in the gridview control or must be change the template of the rowdetails or something else?

and when you click on a row it open up the row details, if not possible my above need how can one close the row details just to click on the same row again? should I ovveright an event or what?

to describe my need more clearly: we need a extra column at the end column as the row details, but this column layout must look different then the other columns because it takes up all  the space left of the grid because is contains only a single row of information(row details of selected row) and
2nd need: when you click on a selected row again it must make that column blank, must works like a deselection of a row.

I just used a toggle button, but still I want to view the row details as an extra colomn.
